The airplane departed Palu-Mutiara Airport on a charter flight to Tolitoli, carrying tourists. En route, the crew descended from 9,000 to 5,000 feet to offer a better view of the area to the passengers when the pilot realized he was facing a mountain. He elected to gain height but the aircraft struck tree tops located on the top of a cliff then stalled and crashed into a ravine. The wreckage was found few hours later. A crew member and nine passengers were rescued while 13 other occupants including both pilots were killed.
